Solved question about RAM speed

July 2, 2012 at 15:38:47
Specs: win 98 SE, 450Mhz/128MB
I recently found some MICRON 256 MB SDRAM memory modules on clear-out sale at an overstock supplier. It says it is a 133 Mhz bus speed, BUT possibly compatible with PC100 bus speeds? (100 Mhz) I have a P3 that desperately needs a RAM upgrade, and i'm not willing to spend 30$ or more on this tower that's on it's last 4 years of life. I can use the RAM in another computer IF it's 100 Mhz compatible. You can see full RAM mfg. specs at: http://download.micron.com/pdf/data...
PS: I'm doing alot of traveling this month so i might not reply for some time if u need more info. sorry!

Just take out the old RAM and put the new sticks in, it should set itself up by itself, well thats what mine did anyway.

I am a hardware guy not a software guy but i try to help.

They should by underclocking the RAM, i put 133MHz RAM in a 100MHz slot and they still worked and my CPU was an celeron 400 MHz ,slot 1.

Unless you post the exact model number of the RAM you're thinking of buying, there's not much anyone can do for you. But I question why you would buy brand new "old RAM"? Aren't there any computer repair shops in your area that might have a drawer full of that stuff? I know I have at least 2 dozen sticks of PC100 & PC133 collecting dust in the basement.

The overstock store had this: MT8LSDT3264AY-13E_. to jay_narr2012: Thank you! i'll try it, just for the heck of it. Do i just stick it in or do i have to fiddle with settings?
to riider: I live in a small town, and the only computer store per say (with a good selection and/or oldie type stuff) is 70 miles away, and i'm not going to drive for 2 hours round trip to get some RAM for an old comp! Sorry, but major shopping is sorta out of the question. i'm stuck with e-bay and Goldmine Electronics, pretty much.

thank You Jay! i've been struggling with this for 6 years, but never gave it any thought after i got my new lappie-top. It runs some old games that i'm still addicted to. I still love those classic lousy MIDI files, the fuzzy graphics, the...... oh, i'm rambling on again! Sorry. Anyway, just wanted to make sure! no need to waste money on unusable Ram. thanks for the help!

The PC133 spec itself is 100% backwards compatible with PC100 and PC66 specs.

However that's not the only thing that determines whether it will work in your mboard or be recognized as it's full size.
See response 5 in this for some info about ram compatibilty:
http://www.computing.net/hardware/w...

E.g. I have an Epox MVP3-G5 mboard that worked fine from the beginning of 2000 until the end of 2010 when two capacitors failed on it. It was designed to be used with PC100 ram but the FSB speed can be slightly overclocked, so I tried PC133 ram with it. Some 256 mb modules that had 8 chips on one side were recognized as half that size, none were recognized as 256 mb, some were not recognized at all; 256 mb modules with 16 chips - 8 chips on each side - were recognized as 256 mb.

Thank you all! the P3 is now happily plugging along with 448mb (BIOS readings) of new-old stock RAM in it! AOE2 now without a hitch!
